title: [A retrospective study of surgery for tumors of the renal parenchyma in adults].
abstract: OBJECTIVE
  To determine the incidence of renal parenchymal tumors in adult patients over the last 30 years, analyze the therapeutic approach and compare radical vs conservative surgery, the surgical principles involved and the survival rates achieved.
  
  
  RESULTS
  We have reviewed 260 cases of renal parenchymal tumors in adults and the utilization of conservative vs radical surgery over the last 30 years. This tumor type has been significantly influenced by the availability of US for routine evaluation, which has led to changes in the clinical features of this condition and the surgical expectations.
  
  
  CONCLUSIONS
  Although the techniques of conservative surgery of the kidney have remained unchanged over the last 50 years, the indications have changed. The incidence of nononcological conditions has decreased while the number of incidentally discovered tumors has increased. The tumor is diagnosed earlier, of smaller size and lower histological grade and stage.
